Walls are preferably formed pziriiilci and are pairzillcl "with tho iongitnilinal plane of the who-3i, and thereby tlicy are not obtrusive to cncountcr obstacles when the yohicle is being driven about; also, in combination with the facing-rm 9 and convorgently formed.

Tho function discharged by rile oonvor curly formcd wall 10 is to furnish a rigid barring which conforms to tho shape of the rubbor tirc, and which supports the Wall of the inflated t-iro for pro 'ciiting blow outs which might occur from inigcrfcotions in the adjacent wali of the tire, this being a similar function already described in ooni'iectiozi with tho ini'ier wail of the tread.
